Explain RS232C Standard.
RS232C:
1. Standard described for asynchronous communications where there is given timing among data bits and no fixed timing among the characters which the bits form.
2. This standard described 25 signal lines and 50ft is the maximum guaranteed distance
3. This standard explains a ser system with only a single wire all direction.
4. Signal levels are: from -25 to -3 and from +3 to +25V.
Explain LDA, STA and DAA instructions LDA copies the data byte into accumulator from the memory location particular by the 16-bit address. STA copies the data byte from the acc

Capacitors : These are electrical condensers having a system of electrical conductors and insulators. The simplest form consists of two parallel metal plates separated by a layer
Electrical circuits and systems : Electrical systems allow energy to be conveniently delivered from the point of supply to the point of application - e.g. electric railways, ca
